When we analyzed the percentage of CD4+ or CD8+ cells expressing CD44hiCD62Llo 30 or 70 days post-infection, we verified that only BCGin/DNA group presented significant expression of CD44hiCD62Llomolecules on CD4+ cells in relation to BCGsc, DNA-HSP65 and infected mice 70 days post-infection (Table 3). This evidence concerns the gene CD4 and infection.
